Answer to Question 1

ANS: A
By increasing FRC and alveolar pressure, auto-PEEP increases the risk and severity of barotrau-ma and volutrauma. Auto-PEEP also increases the work of breathing and impedes venous return, the result being a decrease in cardiac output. Auto-PEEP also can increase pulmonary vascular resistance.

Answer to Question 2

ANS: B
Patients at greatest risk of development of auto-PEEP are those with high airway resistance who are being supported by modes that limit expiratory time.

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt. For the upper point of his scale, he used 96°, which he measured as normal human body temperature (we know it to be 98.6° today because of more accurate thermometers).

Anesthesia awareness is a potentially disturbing adverse effect wherein patients who have been paralyzed with muscle relaxants may awaken. They may be aware of their surroundings but unable to communicate or move. Neurologic monitoring equipment that helps to more closely check the patient's anesthesia stages is now available to avoid the occurrence of anesthesia awareness.
